Yuandong Tian(@tydsh):We introduce TAPA (https://t.co/YpO34Q4Zyp) that decouples magnitude from angular contributions in position encoding. TAPA yields better OOD (long-context) performance than vanilla RoPE approach. We also provide theoretical analysis why it works. Thanks @yusidwang and the colleagues for the great work!
